'Is there any way to distinguish between if the screen was Small, Normal, Large, or X-Large without creating 4 files?

fragment_categories.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.recyclerview.widget.RecyclerView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"
    app:spanCount="2"
    tools:context=".fragments.CategoriesFragment"
    tools:listitem="@layout/row_cateogry" />

I created 4 files of fragment_categories.xml using available qualifiers -> Screen size | Look at UI

  • Small -> app:spanCount="1"
  • Normal -> app:spanCount="1"
  • Large -> app:spanCount="2"
  • X-Large -> app:spanCount="3"

As you noticed I created 4 files of fragment_categories.xml only to change app:spanCount.

Is there any way to distinguish between if the screen was Small, Normal, Large, or X-Large without creating 4 files and without Java, Only in normal XML without available qualifiers?

I can do it in Java in one line to change spanCount, But I have another XML, and more complicated, So it is better to do it in the same XML

I'm using Data Binding Library

androidxmlandroid-xmlandroid-databinding

I am using the library I mentioned below to create a responsive structure.

implementation 'com.intuit.sdp:sdp-android:1.0.5'

This library resizes XML automatically. It doesn't matter if the screen is big or small.

you need to sdp the lengths instead of dp. There is a ratio of 3 to 1 here. For example; If it's 100 dp you need to make an image 33sdp.

I may not have fully understood the question. If I misunderstood you can let me know.
